Abstract
Description
Die Erfindung bezieht sich auf das Gebiet der Herstellung von bespielten Datenträgern in der Form von CDs, DVDs, HD-DVDs und Blueray-Discs, mit Ausnahme von Musik-CDs.The invention relates to the field of production of recorded data carriers in the form of CDs, DVDs, HD-DVDs and Blueray discs, with the exception of music CDs.
Diese Medien als Träger bestimmter Daten werden nach dem derzeitigen Stand der Technik mit Hilfe eines Stampers industriell in großer Zahl gepresst. Anschließend werden sie in einem gesonderten Arbeitsgang auf der Seite über der Reflexionsschicht (Oberseite) mit einem Aufdruck, aus dem sich der Inhalt oder/und werbliche Mitteilungen ergeben, versehen.These media as a carrier of certain data are pressed in the current state of the art with the help of a stampers industrially in large numbers. Subsequently, they are provided in a separate operation on the side above the reflective layer (top) with a print from which the content and / or advertising messages result.
Dieser zweite Arbeitsgang, zumal wenn er nicht im Presswerk ausgeführt wird, verlängert die Produktionszeit und verursacht zusätzliche Druck- und ggf. Transportkosten.This second operation, especially if it is not performed in the press shop, prolongs the production time and causes additional printing and possibly transport costs.
Ferner sind die im Aufdruck verwendeten UV-Farben nicht lebensmittelecht. So bedruckte CDs oder DVDs können daher nicht Lebensmitteln, z.B. Müslipackungen, als Werbeträger oder Dreingabe beigelegt werden.Furthermore, the UV inks used in the imprint are not food safe. Thus printed CDs or DVDs can not be used for food, e.g. Cereal packs, as an advertising medium or a gift.
Die Erfindung besteht darin, die äußerlich sichtbaren Inhalts- oder Werbedarstellungen schon bei der Herstellung der Glassmaster in die Datenfläche der vorerwähnten Medien so zu integrieren,
- dass ein zweiter Arbeitsgang erspart wird und
- es zu keiner gesundheitsschädlichen Reaktion mit Lebensmitteln kommt.
- that a second operation is spared and
- there is no harmful reaction with food.
Dazu wird bei der Herstellung vor dem Aufbrennen der Daten auf den Glassmaster an einer beliebigen Stelle innerhalb der Datenfläche durch das Einfügen von Füllsektoren ein bandförmiges, das heißt sich im Kreis auf dem Datenträger herumziehendes, freies Feld geschaffen. Bei dem Beschreiben des Datenträgers wird dieser Sektor, da durch Leerzeichen schon belegt, nicht aufgerufen, d.h. nicht überschrieben, sondern ausgelassen. Dadurch bleibt diese Fläche für das gesonderte Aufbringen von nach außen sichtbaren, d.h. mit bloßem Auge erkennbaren, grafischen oder textlichen Mitteilungen frei.For this purpose, in the production before the burning of the data on the Glassmaster at any point within the data area by the insertion of Füllsektoren a band-shaped, that is created in a circle on the disk herumziehendes, free field. In describing the volume, this sector is not called because it is already occupied by spaces. not overwritten, but omitted. Thereby, this surface remains for the separate application of externally visible, i. with the naked eye recognizable, graphic or text messages freely.
Auch die Schaffung mehrerer, parallel zueinander verlaufender, ringförmiger, freier Flächen ist möglich.It is also possible to create a plurality of mutually parallel, annular, free surfaces.
Die außen auf dem Datenträger sichtbaren Text- oder Grafiksymbole werden in einem zweiten Arbeitsgang in die freigelassenen Felder auf dem Glassmaster eingefügt. Dazu werden Grafik- oder Schriftsymbole vermittels eines Laserstrahlgerätes aus der Fotoresistlackschicht des Glassmasters heraus= gebrannt. Anschließend wird der Glassmaster vollständig ausentwickelt. Dadurch werden die Symbole auf der Oberseite einfarbig weiß sichtbar. Dann folgen das im Herstellungsverfahren übliche Sputtern und Galvanisieren. Von dem fertigen Glassmaster wird sodann der für die Massenproduktion notwendige Stamper hergestellt.The text or graphic symbols visible externally on the data carrier are inserted in a second step in the released fields on the Glassmaster. For this graphics or writing symbols are burnt out by means of a laser beam device from the photoresist layer of the glass master =. Then the Glassmaster is fully developed. As a result, the symbols on the top are visible in monochrome white. This is followed by the customary sputtering and electroplating in the production process. The stamper necessary for mass production is then produced from the finished glass master.
Da den auf den Datenträgern aufgebrachten Daten jeweils eine bestimmte Adresse auf dem Datenfeld zugeordnet ist, auf der mit dem Informations- bzw. Werbeaufdruck versehenen Fläche jedoch keine Daten vorhanden sind, wird diese beim Abspielen des Datenträgers von vornherein nicht aufgerufen, sondern übersprungen und stört die Benutzung daher nicht.Since the data applied to the data carriers in each case a specific address is assigned to the data field on the provided with the information or advertising print surface, however, no data is present, this is not called when playing the disk from the outset, but skipped and disturbs the Use therefore not.
Durch die Erfindung muss nicht mehr jeder einzelne Datenträger in zwei Arbeitsgängen hergestellt werden sondern nur noch der Glassmaster. Von dem davon hergestellten Stamper können dann eine Vielzahl fertiger Datenträger gezogen werden, die nicht mehr nachbearbeitet werden müssen.Due to the invention, it is no longer necessary to produce each individual data carrier in two working steps, but only the glass master. From the stamper produced by it can then be drawn a variety of finished media that does not need to be reworked.
Der Aufwand, den Glassmaster in zwei Arbeitsgängen herzustellen, ist ungleich geringer und vor allem kostengünstiger als der, der mit dem separaten Bedrucken jedes einzelnen Datenträgers verbunden ist.The effort required to produce the Glassmaster in two operations is much lower and, above all, less expensive than the one associated with the separate printing of each individual medium.
